Hi Andy do you mean the 100 ohm res is in series from pin 10 of the arduino to the cathode + side  of the zener diode and then the anode is down to ground? as that would be th way I would do it.
Thanks Andy.

Here is a schematic I use. If you change the resistor value it will change the voltage out to the PE.

Thanks Andy this was what I thought it would be.
Just out of curiosity why is the circuit showing 2 zener diode one of them is floating or not conected?

That was just a stock symbol that had the footprint I needed when designing the pcb. The part I used has a pinout of 1- Anode, 2 - No Connection, 3 - Cathode.
